This cabinet card hails from Ottawa, Illinois. Since there is a stamp on the back that reads “Duplicate Ordered. Mar 1892” I would assume that the photo was taken around that time. Unfortunately there is no identifying information for the woman in the photograph.
The photographer is W. E. Bowman (William Emory) and in the lower left on the back of the card it states that the gallery was established in 1865. You can read more about the photographer in the article “Bowman Was a Big Name in Photography” by Mollie Perrot.
